js code to disable button for 5 seconds_form effects

First give a good code:

<input type="button" value="失效5秒" onclick="setTimeout((function(me){me.disabled=true;return function(){me.disabled=false;};})(this),5000);">
[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute ]

The second type Not bad either

<input type="button" value=" 失效5秒 " onclick="{ this.disabled = true; var me = this; setTimeout(function() { me.disabled = false; }, 5000); }">
[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute ]

The third one is more streamlined

<input type="button" value=" 失效5秒 " id="me" onclick="this.disabled=true;setTimeout('me.disabled=false',5000);">
[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute ]

The key is that setTimeout is the first This in the first parameter is window, so a more practical variable
is needed. It is not feasible to directly rely on this in setTimeout, because it points to window, which can be achieved by globalizing the node that wants to be processed.
Fengyan’s method is to pass in the correct this reference before setTimeout executes the countdown, and return a required package with the correct node reference.
is the execution function after setTimeout counts down. It doesn't matter whether the parameter name is me or Mes.
